 # Hermes Web UI -- Changelog
 
+## [v0.50.63] — 2026-04-16
+
+### Fixed
+- **Onboarding wizard no longer fires for non-standard providers** — providers outside the quick-setup list (`minimax-cn`, `deepseek`, `xai`, `gemini`, etc.) were always evaluated as `chat_ready=False` because `_provider_api_key_present()` only knew the four built-in env-var names. Those users saw the wizard on every page load and risked `config.yaml` being silently overwritten if the provider dropdown defaulted. The fix adds a `hermes_cli.auth.get_auth_status()` fallback covering every API-key provider in the full registry, and tightens the frontend guard so an unchanged unsupported-provider form never POSTs. (Fixes #572, PR #575)
+- **MCP server toolsets now included in WebUI agent sessions** — previously the WebUI read `platform_toolsets.cli` directly from `config.yaml`, which only carries built-in toolset names. MCP server names (`tidb`, `kyuubi`, etc.) were silently dropped, so MCP tools configured via `~/.hermes/config.yaml` were unavailable in chat. The fix delegates to `hermes_cli.tools_config._get_platform_tools()` — the same code the CLI uses — which merges all enabled MCP servers automatically. Falls back gracefully when `hermes_cli` is unavailable. (PR #574 by @renheqiang)
+
+## [v0.50.62] — 2026-04-16
+
+### Fixed
+- **Docker startup no longer hard-exits when hermes-agent source is not mounted** — previously `docker_init.bash` would call `error_exit` if the agent source directory was missing, preventing the container from starting at all. Users running a minimal `docker run` without the two-container compose setup hit this immediately. Now the script checks for the directory and `pyproject.toml` first, prints a clear warning explaining reduced functionality, and continues startup. The WebUI already has `try/except` fallbacks throughout for when hermes-agent is unavailable. (Fixes #570, PR #573)
+
+## [v0.50.61] — 2026-04-16
+
+### Added
+- **Office file attachments** — `.xls`, `.xlsx`, `.doc`, and `.docx` files can now be selected via the attach button. The file picker's `accept` attribute is extended to include Office MIME types, and the backend MIME map is updated so these files are served with correct content-type headers when accessed through the workspace file browser. Files are saved as binary to the workspace; the AI can reference them by name the same way it does PDFs. (PR #566 by @renheqiang)
+
+## [v0.50.60] — 2026-04-16
+
+### Changed
+- **Test robustness** — two onboarding setup tests (`test_setup_allowed_with_confirm_overwrite`, `test_setup_allowed_when_no_config_exists`) now skip gracefully when PyYAML is not installed in the test environment, matching the pattern already used in `test_onboarding_mvp.py`. No production code changed. (PR #564)
+
+## [v0.50.59] — 2026-04-16
+
+### Fixed
+- **False "Connection lost" message after settled stream** — the UI no longer injects a fake `**Error:** Connection lost` assistant message when an SSE connection drops after the stream already completed normally. The fix tracks terminal stream states (`done`, `stream_end`, `cancel`, `apperror`) and, on a disconnect, fetches `/api/session` to confirm the session is settled before silently restoring it instead of calling the error path. Real failures still go through the error path as before. (Fixes #561, PR #562 by @halmisen)
+
+## [v0.50.58] — 2026-04-16
+
+### Fixed
+- **Custom provider name in model dropdown** — when a `custom_providers` entry in `config.yaml` has a `name` field (e.g. `Agent37`), the model picker now shows that name as the group header instead of the generic `Custom` label. Multiple named providers each get their own group. Unnamed entries still fall back to `Custom`. Brings the web UI into parity with the terminal's provider display. (Fixes #557)
+
+## [v0.50.57] — 2026-04-15
+
+### Added
+- **Auto-generated session titles** — after the first exchange, a background thread generates a concise title from the first user message and assistant reply, replacing the default first-message substring. Updates live in the UI via a new `title` SSE event. Manual renames are preserved; generation only runs once per session. Includes MiniMax token budget handling and a local heuristic fallback. (Fixes #495, PR #535 by @franksong2702)
+
+### Changed
+- **SSE stream termination** — streams now end with `stream_end` instead of `done` so the background title generation thread has time to emit the title update before the client disconnects.
+
+## [v0.50.55] — 2026-04-15
+
+### Fixed
+- **Docker honcho extra** — `docker_init.bash` now installs `hermes-agent[honcho]` so `honcho-ai` is included in the venv on every fresh Docker build. Fixes `"Honcho session could not be initialized."` errors on rebuilt containers. (Fixes #553)
+- **Version badge** — `index.html` version badge corrected to v0.50.55 (was missing the bump for this release).
+
+## [v0.50.54] — 2026-04-15
+
+### Changed
+- **OpenRouter model list** — updated to 14 current models across 7 providers. All slugs verified live against the OpenRouter catalog. Removed `o4-mini`, old Gemini 2.x entries, and Llama 4. Added Claude Opus 4.6, GPT-5.4, Gemini 3.1 Pro Preview, Gemini 3 Flash Preview, DeepSeek R1, Qwen3 Coder, Qwen3.6 Plus, Grok 4.20, and Mistral Large. Both Claude 4.6 and 4.5 generations preserved. Fixed `grok-4-20` → `grok-4.20` slug and Gemini `-preview` suffixes.
+
+## [v0.50.53] — 2026-04-15
+
+### Fixed
+- **Custom endpoint slash model IDs** — model IDs with vendor prefixes that are intrinsic (e.g. `zai-org/GLM-5.1` on DeepInfra) are now preserved when routing to a custom `base_url` endpoint. Previously, all prefixed IDs were stripped, causing `model_not_found` errors on providers that require the full vendor/model format. Known provider namespaces (`openai/`, `google/`, `anthropic/`, etc.) are still stripped as before. (Fixes #548, PR #549 by @eba8)
+
+## [v0.50.52] — 2026-04-15
+
+### Fixed
+- **Simultaneous approval requests** — parallel tool calls that each require approval no longer overwrite each other. `_pending` is now a list per session; each entry gets a stable `approval_id` (uuid4) so `/api/approval/respond` can target a specific request. The UI shows a "1 of N pending" counter when multiple approvals are queued. Backward-compatible with old agent versions and old frontend clients. Adds 14 regression tests. (Fixes #527)
+
+## [v0.50.51] — 2026-04-15
+
+### Fixed
+- **Orphaned tool messages** — conversation histories containing `role: tool` messages with no matching `tool_call_id` in a prior assistant message are now silently stripped before sending to the provider API. Fixes 400 errors from strictly-conformant providers (Mercury-2/Inception, newer OpenAI models). Adds 13 regression tests. (Fixes #534)
+
+## [v0.50.50] — 2026-04-15
+
+### Fixed
+- **Code block syntax highlighting** — Prism theme now follows the active UI theme. Light mode uses the default Prism light theme; dark mode uses `prism-tomorrow`. Theme swaps happen immediately on toggle including on first load. Adds `id="prism-theme"` to the Prism CSS link so JavaScript can locate and swap it. (Closes #505, PR #530 by @mariosam95)
+
+## [v0.50.49] — 2026-04-15
+
+### Fixed
+- **IME composition** — `isComposing` guard added to every Enter keydown handler so CJK/Japanese/Korean input method users never accidentally send mid-composition (fixes #531). Covers chat composer, command dropdown, session rename, project create/rename, app dialog, message edit, and workspace rename. Adds 3 regression tests. (PR #537 by @vansour)
+
+## [v0.50.48] fix: toast when model is switched during active session (#419)
+
+Synthesized from PRs #516 (armorbreak001), #517 and #518 (cloudyun888).
+
+When a user switches the model via the model picker while a session already
+has messages, a 3-second toast now reads: "Model change takes effect in
+your next conversation." This avoids the confusing situation where the
+dropdown shows the new model but the current conversation continues with
+the original one.
+
+The toast fires from `modelSelect.onchange` in `static/boot.js`, after the
+existing provider-mismatch warning. It checks `S.messages.length > 0` (the
+reliable in-memory array, always initialized by `loadSession`). The
+`showToast` call is guarded with `typeof` for safety during boot.
+
+Key differences from submitted PRs: placement in boot.js onchange (covers
+all selection paths including chip dropdown, since `selectModelFromDropdown`
+calls `sel.onchange`), and uses `S.messages` not `S.session.messages`.
+
+4 new tests in `tests/test_provider_mismatch.py::TestModelSwitchToast`.
+
+Total tests: 1272 (was 1268)
+
+
+## [v0.50.47] fix/feat: batch fixes — root workspace, custom providers, cron cache, system theme
+
+Synthesized from PRs #506, #507, #508, #509, #510, #514, #515, #519, #521.
+
+### Fixes
+
+**Allow /root as a workspace path** (PRs #510, #521 by @ccqqlo)
+Removes `/root` from `_BLOCKED_SYSTEM_ROOTS` in `api/workspace.py`, so
+deployments running as root (Docker, VPS) can set `/root` as their workspace
+without a "system directory" rejection.
+
+**Guard against split on missing [Attached files:]** (PR #521 by @ccqqlo)
+`base_text` extraction in `api/streaming.py` now guards: `msg_text.split(...)[0]
+if ... in msg_text else msg_text`. Previously split on the empty case returned
+an empty string, causing attachment-matching to silently fail on messages with
+no attachments.
+
+**custom_providers models visible regardless of active provider** (#515, #519 by @shruggr, @cloudyun888)
+`get_available_models()` in `api/config.py` no longer discards the 'custom'
+provider from `detected_providers` when the user has `custom_providers` entries
+in `config.yaml`. Previously, switching active_provider away from 'custom'
+hid all custom model definitions from the picker.
+
+**Cron skill picker cache invalidated on form open and skill save** (PRs #507, #508 by @armorbreak001)
+`toggleCronForm()` now unconditionally nulls `_cronSkillsCache` before fetching,
+so skills created in the same session appear immediately. `submitSkillSave()` also
+nulls `_cronSkillsCache` after a successful write, mirroring the existing
+`_skillsData = null` pattern. Fixes #502.
+
+### Features
+
+**System (auto) theme following OS prefers-color-scheme** (#504 / PRs #506, #509, #514 by @armorbreak001, @cloudyun888)
+New "System (auto)" option in the theme picker follows the OS dark/light preference
+via `window.matchMedia`. Changes:
+- `static/boot.js`: `_applyTheme(name)` helper resolves 'system' via matchMedia,
+  sets `data-theme`, and registers a MQ change listener for live OS tracking.
+  `loadSettings()` calls `_applyTheme()` instead of direct assignment.
+- `static/index.html`: flicker-prevention script resolves 'system' before first
+  paint. Adds "System (auto)" as first theme option. onchange calls `_applyTheme()`.
+- `static/commands.js`: adds 'system' to valid `/theme` names.
+- `static/panels.js`: `_settingsThemeOnOpen` reads from localStorage (preserves
+  'system' string). `_revertSettingsPreview` calls `_applyTheme()`.
+- `static/i18n.js`: cmd_theme description lists 'system' first in all 5 locales.

+
+## [v0.50.46] feat: clarify dialog flow and refresh recovery (#520)
+
+Adds a full clarify dialog UX for interactive agent questions — modeled after
+the approval card but for free-form clarification prompts.
+
+### Backend
+
+New `api/clarify.py` module with a per-session pending queue backed by
+`threading.Event` unblocking, gateway notify callbacks, duplicate deduplication
+while unresolved, and resolve/clear helpers.
+
+Three new HTTP endpoints in `api/routes.py`:
+- `GET /api/clarify/pending` — poll for pending clarify prompt
+- `POST /api/clarify/respond` — resolve the pending prompt
+- `GET /api/clarify/inject_test` — loopback-only, for automated tests
+
+`api/streaming.py` wires `clarify_callback` into `AIAgent.run_conversation()`.
+Emits `clarify` SSE events; blocks the tool flow until the user responds, times
+out (120s), or the stream is cancelled. Also adds a 409 guard on `chat/start` so
+page-refresh races return the active stream id instead of starting a duplicate.
+
+### Frontend
+
+`static/messages.js`: clarify card with numbered choices, Other button, and
+free-text input. Composer is locked while clarify is active. DOM self-heals if
+the card node is removed during a rerender. SSE `clarify` event listener plus
+1.5s fallback polling. Session switch and reconnect start/stop clarify polling.
+409 conflict flow reattaches to the active stream and queues the user message.
+`CLARIFY_MIN_VISIBLE_MS = 30000` timer dedup mirrors the approval card pattern.
+
+`static/ui.js`: `lockComposerForClarify()` / `unlockComposerForClarify()` with
+saved-state restore. `updateSendBtn()` respects the disabled state.
+
+`static/sessions.js`: `loadSession()` starts/stops clarify polling on switch
+and inflight reattach.
+
+`static/index.html` / `static/style.css`: clarify card markup with ARIA roles
+and full responsive/mobile styles.
+
+`static/i18n.js`: 6 new keys in all 5 locales (en, es, de, zh-Hans, zh-Hant).
+
+### Tests
+
+- `tests/test_clarify_unblock.py`: 14 new tests covering queue resolution,
+  notify callbacks, clear-on-cancel, and all three HTTP endpoints.
+- `tests/test_sprint30.py`: 31 new clarify tests (HTML markup, CSS classes,
+  i18n keys, messages.js functions, streaming registration flags).
+- `tests/test_sprint36.py`: expand search window for `setBusy` check after
+  additional `stopClarifyPolling()` calls push it past the old 800-char limit.
+
+Total tests: 1246 (was 1209)

+
+
+## [v0.50.45] fix: suppress N/A source_tag in session list (#429)
+
+Feishu and WeChat sessions (and any session with an unrecognised or legacy
+`source` value in hermes-agent's state.db) were showing "N/A" or raw tag
+strings in the session list sidebar.
+
+Three fixes in `static/sessions.js`:
+
+1. `_formatSourceTag()` now returns `null` for unrecognised tags instead of
+   the raw string. Known platforms (telegram, discord, slack, feishu, weixin,
+   cli) still display their human-readable label. Unknown/legacy values are
+   silently suppressed.
+
+2. The `metaBits` push is guarded: stores the result in `_stLabel` and only
+   pushes if it is non-null. Prevents `null` or unrecognised platform names
+   from appearing in the session metadata line.
+
+3. The `[SYSTEM:]` title fallback now uses `_SOURCE_DISPLAY[s.source_tag] ||
+   'Gateway'` — the raw `s.source_tag` middle term is removed so a session
+   whose source is "N/A" does not use that as its visible title.
+
+No backend changes. The upstream issue (hermes-agent not reliably setting
+`source` for older Feishu/WeChat sessions) is tracked separately.
+
+7 new tests in `tests/test_issue429.py`. Updated 1 existing test in
+`tests/test_sprint40_ui_polish.py` to match the new guarded push pattern.
+

+
+## [v0.50.44] fix: code-in-table CSS sizing + markdown image rendering (#486, #487)
+
+**CSS: inline code inside table cells** (fixes #486)
+
+Inline `` `code` `` spans inside `<td>` and `<th>` cells were rendering too
+large relative to the cell height — the `.msg-body code` rule sets `12.5px`
+which sits awkward against the table's `12px` base font.
+
+Fix: added two targeted rules in `static/style.css`:
+
+    .msg-body td code,.msg-body th code { font-size:0.85em; padding:1px 4px; vertical-align:baseline; }
+    .preview-md td code,.preview-md th code { font-size:0.85em; padding:1px 4px; vertical-align:baseline; }
+
+Covers both the chat message surface (`.msg-body`) and the markdown preview
+panel (`.preview-md`).
+
+**JS renderer: `![alt](url)` image syntax** (fixes #487)
+
+Standard markdown image syntax was not handled by `renderMd()`. The `!` was
+left as a stray character and `[alt](url)` was consumed by the link pass,
+producing `! <a href="url">alt</a>` instead of an `<img>`.
+
+Fix: added an image pass to both `inlineMd()` (for images in table cells,
+list items, blockquotes, headings) and the outer `renderMd()` pipeline (for
+images in plain paragraphs):
+
+- Regex: `![alt](https?://url)` — only `http://` and `https://` URIs accepted;
+  `javascript:` and `data:` URIs cannot match.
+- Alt text passes through `esc()` — XSS-safe.
+- URL double-quotes percent-encoded to `%22` — attribute breakout prevented.
+- Reuses `.msg-media-img` class — same click-to-zoom and max-width styling as
+  agent-emitted `MEDIA:` images.
+- `img` added to `SAFE_TAGS` allowlist so the generated `<img>` is not escaped.
+- In `inlineMd()`: image pass runs while the `_code_stash` is still active,
+  so `![alt](url)` inside a backtick span stays protected and is never rendered
+  as an image. A new `_img_stash` (`\x00G`) protects rendered `<img>` tags
+  from the autolink pass touching `src=` values.
+
+**Tests**
+
+45 new tests in `tests/test_issue486_487.py`:
+- 13 CSS source checks and rendering tests for #486
+- 22 JS source checks and rendering tests for #487
+- 10 combination edge cases (code + image + link all in same table)
+
+- Total tests: 1195 (was 1150)
+
+## [v0.50.43] fix: markdown link rendering + KaTeX CSP fonts
+
+**Markdown link rendering — `renderMd()` in `static/ui.js`** (PR #475, fixes #470)
+
+Three related bugs fixed:
+
+1. **Double-linking via autolink pass** — `[label](url)` was converted to `<a href="...">`, then the bare-URL autolink pass re-matched the URL sitting inside `href="..."` and wrapped it in a second `<a>` tag. Fixed with three stash/restore layers: `\x00L` (inlineMd labeled links), `\x00A` (existing `<a>` tags before outer link pass), `\x00B` (existing `<a>` tags before autolink pass).
+
+2. **`esc()` on `href` values corrupts query strings** — `esc()` is HTML-entity encoding; applying it to URLs converted `&` → `&amp;` in query strings. Removed `esc()` from href values in all three locations. Display text (link labels) still uses `esc()` for XSS safety. `"` in URLs replaced with `%22` (URL encoding) to close the attribute-injection vector identified during review.
+
+3. **Backtick code spans inside `**bold**` rendered as `&lt;code&gt;`** — `esc()` was applied to code spans after bold/italic processing. Added `\x00C` stash to protect backtick spans in `inlineMd()` before bold/italic regex runs.
+
+**Security audit:** `javascript:` injection blocked by `https?://` prefix requirement. `"` attribute breakout fixed by `.replace(/"/g, '%22')`. Label/display text still HTML-escaped.
+
+24 tests in `tests/test_issue470.py`.
+
+**KaTeX CSP font-src** (fixes #477)
+
+`api/helpers.py` CSP `font-src` now includes `https://cdn.jsdelivr.net` so KaTeX math rendering fonts load correctly. Previously ~50 CSP font-blocking errors appeared in the console on any page with math content. The CDN was already allowed in `script-src` and `style-src` for KaTeX JS/CSS — this extends the same allowance to fonts.
+
+3 tests in `tests/test_issue477.py`.

+
+## [v0.50.42] fix: session display + model UX polish (sprint 42)
+
+**Context indicator always shows latest usage** (PR #471, fixes #437)
+The context ring/indicator in the composer footer was reading token counts and cost
+from the stored session snapshot with `||` — meaning stale non-zero values from
+previous turns always won over a fresh `0` from the current turn. Replaced all six
+field merges with a `_pick(latest, stored, dflt)` helper that correctly prefers the
+latest usage when it's a real value (including `0`).
+
+**System prompt no longer leaks as gateway session title** (PR #472, fixes #441)
+Telegram, Discord, and CLI gateway sessions inject a system message before any user
+turn. When the session title is set from this message, the sidebar shows
+`[SYSTEM: The user has inv...` instead of a meaningful name. Added a guard in
+`_renderOneSession()`: if `cleanTitle` starts with `[SYSTEM:`, replace it with the
+platform display name (`Telegram session`, `Discord session`, etc.).
+
+**Thinking/reasoning panel persists across page reload** (PR #473, fixes #427)
+The full chain-of-thought from Claude, Gemini, and DeepSeek thinking models was lost
+after streaming completed and on every page reload. Two-part fix:
+- `api/streaming.py`: `on_reasoning()` now accumulates `_reasoning_text`; before the
+  session is serialised at stream end, `_reasoning_text` is injected into the last
+  assistant message so it's stored in the session JSON
+- `static/messages.js`: in the `done` SSE handler, `reasoningText` is also patched
+  onto the last assistant message as a belt-and-suspenders client-side fallback
+
+**Custom model ID input in model picker** (PR #474, fixes #444)
+Users who need a model not in the curated list (~30 models) can now type any model
+ID directly in the dropdown. A text input at the bottom of the model picker lets
+users enter any string (e.g. `openai/gpt-5.4`, `deepseek/deepseek-r2`, or any
+provider-prefixed ID) and press Enter or click + to use it immediately.

+## [v0.50.41] feat(ui): render MEDIA: images inline in web UI chat (fixes #450)
+
+When the agent outputs `MEDIA:<path>` tokens — screenshots from the browser tool,
+generated images, vision outputs — the web UI now renders them **inline in the chat**,
+the same way Claude.ai handles images. No more relaying screenshots through Telegram.
+
+**How it works:**
+- Local image path (`MEDIA:/tmp/screenshot.png`): rendered as `<img>` via `/api/media?path=...`
+- HTTP(S) URL to image (`MEDIA:https://example.com/img.png`): `<img>` directly from the URL
+- Non-image file (`MEDIA:/tmp/report.pdf`): styled download link (📎 filename)
+- Click any inline image to toggle full-size zoom
+
+**New endpoint — `GET /api/media?path=<encoded-path>`:**
+- Path allowlist: `~/.hermes/`, `/tmp/`, active workspace — covers all agent output locations
+- Auth-gated: requires valid session cookie when auth is enabled
+- Inline image MIME types: PNG, JPEG, GIF, WebP, BMP
+- SVG always served as download attachment (XSS prevention)
+- RFC 5987-compliant `Content-Disposition` headers (handles Unicode filenames)
+- `Cache-Control: private, max-age=3600`
+
+**Security:**
+- Original version had `~` (entire home dir) as an allowed root — **fixed** by independent reviewer
+- Restricted to `~/.hermes/`, `/tmp/`, and active workspace only
+- `Path.resolve()` + `commonpath` checks prevent symlink traversal
+
+**Changes:**
+- `api/routes.py`: `_handle_media()` handler + `/api/media` route

+## [v0.50.40] feat: session UI polish + parallel test isolation
+
+**Session sidebar improvements:**
+- `static/sessions.js` + `style.css`: Hide session timestamps to give titles full available width — no more title truncation from inline timestamps (PR #449)
+- `static/style.css`: Active session title now uses `var(--gold)` theme variable instead of hardcoded `#e8a030` — adapts correctly across all 7 themes (PR #451, fixes #440)
+- `api/models.py` + `api/gateway_watcher.py`: Return `None` instead of the string `'unknown'` for missing gateway session model — Telegram sessions no longer show `telegram · unknown` (PR #452, fixes #443)
+- `static/style.css` + `static/sessions.js`: Mute Telegram badge from saturated `#0088cc` to `rgba(0, 136, 204, 0.55)`. Add `_formatSourceTag()` helper mapping platform IDs to display names (`telegram` → `via Telegram`) (PR #453, fixes #442)
+
+**Bug fixes:**
+- `api/config.py` `resolve_model_provider()`: Strip provider prefix from model ID when a custom `base_url` is configured (`openai/gpt-5.4` → `gpt-5.4`) — fixes broken chats after switching to a custom endpoint (PR #454, fixes #433)
+- `static/panels.js` `switchToProfile()`: Apply profile default workspace to new session created during profile switch — workspace chip no longer shows "No active workspace" after switching profiles mid-conversation (PR #455, fixes #424)
+
+**Test infrastructure:**
+- `tests/conftest.py` + `tests/_pytest_port.py` (new): Auto-derive unique port and state dir per worktree from repo path hash (range 20000-29999). Running pytest in two worktrees simultaneously no longer causes port conflicts. All 43 test files updated from hardcoded `BASE = "http://127.0.0.1:8788"` to `from tests._pytest_port import BASE` (PR #456)

+## [v0.50.39] fix: orphan gateway sessions + first-password-enablement session continuity
+
+Two bug fixes:
+
+**PR #423 — Fix orphan gateway sessions in sidebar (@aronprins, fix by maintainer)**
+`gateway_watcher.py`'s `_get_agent_sessions_from_db()` was missing the
+`HAVING COUNT(m.id) > 0` clause that `get_cli_sessions()` already had. Sessions
+with no messages (e.g. created then abandoned before any turns) would appear in the
+sidebar via the SSE watcher stream even after the initial page load filtered them out.
+One-line SQL fix applied to both query paths.
+
+**PR #434 — First-password-enablement session continuity (@SaulgoodMan-C)**
+When a user enables a password for the first time via POST `/api/settings`,
+the current browser session was being terminated — requiring the user to log in
+again immediately after setting their password. Fix: the response now includes
+`auth_enabled`, `logged_in`, and `auth_just_enabled` fields, and issues a
+`hermes_session` cookie when auth is first enabled, so the browser remains logged in.
+Also: legacy `assistant_language` key is now dropped from settings on next save.
+New i18n keys for password replacement/keep-existing states (en, es, de, zh, zh-Hant).
+
+- `api/config.py`: `_SETTINGS_LEGACY_DROP_KEYS` removes `assistant_language` on load
+- `api/routes.py`: first-password-enable session continuity with `auth_just_enabled` flag
+- `static/panels.js`: `_setSettingsAuthButtonsVisible()` + `_applySavedSettingsUi()` helpers
+- `static/i18n.js`: password state i18n keys across 5 locales
+- `tests/test_sprint45.py`: 3 new integration tests (auth continuity + legacy key cleanup)
+
+- Total tests: 1078 (was 1075)
+
+
+## [v0.50.38] feat: mobile nav cleanup, Prism syntax highlighting, zh-CN/zh-Hant i18n
+
+Three community contributions combined:
+
+**PR #425 — Remove mobile bottom nav (@aronprins)**
+The fixed iOS-style bottom navigation bar on phones has been removed. The sidebar drawer
+tabs already handle all navigation — the bottom nav was redundant and consumed ~56px of
+vertical chat space. `test_mobile_layout.py` updated with `test_mobile_bottom_nav_removed()`
+and new sidebar nav coverage tests.
+
+**PR #426 — Prism syntax highlighting with light + dark theme token colors (@GiggleSamurai)**
+Fenced code blocks now emit `class="language-{lang}"` on `<code>` elements, enabling Prism's
+autoloader to apply token-level syntax highlighting. Added 36-line `:root[data-theme="light"]`
+token color overrides scoped to light theme only; dark/dim/monokai/nord themes unaffected.
+Background guard uses `var(--code-bg) !important` to prevent Prism's dark background from
+overriding theme variables. 2 new regression tests in `test_issue_code_syntax_highlight.py`.
+
+**PR #428 — zh-CN/zh-Hant i18n hardening (@vansour)**
+Pluggable `resolvePreferredLocale()` function with smart zh-CN/zh-SG/zh-TW/zh-HK variant
+mapping. Full zh-Simplified and zh-Traditional locale blocks added to `i18n.js`. Login page
+locale routing updated in `api/routes.py` (`_resolve_login_locale_key()` helper). Hardcoded
+strings in `panels.js` cron UI extracted to i18n keys. 3 new test files:
+`test_chinese_locale.py`, `test_language_precedence.py`, `test_login_locale.py`.
+
+- Total tests: 1075 (was 1063)
+
+## [v0.50.37] fix(onboarding): skip wizard when Hermes is already configured
+
+Fixes #420 — existing Hermes users with a valid `config.yaml` were shown the first-run
+onboarding wizard on every WebUI load because the only completion gate was
+`settings.onboarding_completed` in the WebUI's own settings file. Users who configured
+Hermes via the CLI before the WebUI existed had no such flag, so the wizard always fired
+and could silently overwrite their working config.
+
+**Changes:**
+1. `api/onboarding.py` `get_onboarding_status()`: auto-complete when `config.yaml` exists
+   AND `chat_ready=True`. Existing configured users are never shown the wizard.
+2. `api/onboarding.py` `apply_onboarding_setup()`: refuse to overwrite an existing
+   `config.yaml` without `confirm_overwrite=True` in the request body. Returns
+   `{error: "config_exists", requires_confirm: true}` for the frontend to handle.
+3. `static/index.html`: "Skip setup" button added to wizard footer — users are never
+   trapped in the wizard.
+4. `static/onboarding.js`: `skipOnboarding()` calls `/api/onboarding/complete` without
+   modifying config, then closes the overlay.
+5. `static/boot.js`: Escape key now dismisses the onboarding overlay.
+6. `static/i18n.js`: `onboarding_skip` / `onboarding_skipped` keys added to en + es locales.
+7. `tests/test_onboarding_existing_config.py`: 8 new unit tests covering gate logic and
+   overwrite guard.
+
+- Total tests: 1063 (was 1055)
+
+
+## [v0.50.36] fix: workspace list cleaner — allow own-profile paths, remove brittle string filter
+
+Two bugs in `_clean_workspace_list()` caused workspace additions to silently disappear on the next `load_workspaces()` call, breaking `test_workspace_add_no_duplicate` and `test_workspace_rename` (and potentially causing real-world workspace list corruption):
+
+**Bug 1 — Brittle string filter removed:** `if 'test-workspace' in path or 'webui-mvp-test' in path: continue` dropped any workspace path containing those substrings. In the test server, `TEST_WORKSPACE` is `~/.hermes/profiles/webui/webui-mvp-test/test-workspace`, so every workspace added during tests was silently discarded on the next `load_workspaces()` call. The `p.is_dir()` check already handles genuinely non-existent paths — the string filter was redundant and harmful.
+
+**Bug 2 — Cross-profile filter was too broad:** `if p is under ~/.hermes/profiles/: skip` was designed to block cross-profile workspace leakage, but it also removed paths under the *current* profile's own directory (e.g. `~/.hermes/profiles/webui/...`). Fixed: now only skips paths under `profiles/` that are NOT under the current profile's own `hermes_home`.
+
+- `api/workspace.py`: remove string-match filter; fix cross-profile check to allow own-profile paths
+- All 1055 tests now pass (was 1053 pass + 2 fail)
+
+## [v0.50.35] fix: workspace trust boundary — cross-platform, multi-workspace support
+
+v0.50.34's workspace trust check was too restrictive: it required all workspaces to be under `DEFAULT_WORKSPACE` (/home/hermes/workspace), which blocked every profile-specific workspace (~/CodePath, ~/hermes-webui-public, ~/WebUI, ~/Camanji, etc.) and prevented switching between workspaces at all.
+
+Replaced with a three-layer model that works cross-platform and supports multiple workspaces per profile:
+
+1. **Blocklist** — `/etc`, `/usr`, `/var`, `/bin`, `/sbin`, `/boot`, `/proc`, `/sys`, `/dev`, `/root`, `/lib`, `/lib64`, `/opt/homebrew` always rejected, closing the original CVSS 8.8 vulnerability
+2. **Home-directory check** — any path under `Path.home()` is trusted; `Path.home()` is cross-platform (`~/...` on Linux/macOS, `C:\\Users\\...` on Windows); allows all profile workspaces simultaneously since they don't need to share a single ancestor
+3. **Saved-workspace escape hatch** — paths already in the profile's saved workspace list are trusted regardless of location, covering self-hosted deployments with workspaces outside home (`/data/projects`, `/opt/workspace`, etc.)
+
+- `api/workspace.py`: rewritten `resolve_trusted_workspace()` with the three-layer model
+- `tests/test_sprint3.py`: updated error-message assertions from `"trusted workspace root"` → `"outside"` (covers both old and new error strings)
+- 1053 tests total (unchanged)
+
+## [v0.50.34] fix(workspace): restrict session workspaces to trusted roots [SECURITY] (#415)
+
+Session creation, update, chat-start, and workspace-add endpoints accepted arbitrary caller-supplied workspace paths. An authenticated caller could repoint a session to any directory the process could access, then use normal file read/write APIs to operate on attacker-chosen locations. CVSS 8.8 High (AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H).
+
+- `api/workspace.py`: new `resolve_trusted_workspace(path)` helper — resolves path, checks existence + is_dir, enforces `path.relative_to(_BOOT_DEFAULT_WORKSPACE)` containment; requests outside the WebUI workspace root fail with 400
+- `api/routes.py`: apply `resolve_trusted_workspace()` to all four entry points — `POST /api/session/new`, `POST /api/session/update`, `POST /api/chat/start` (workspace override), `POST /api/workspaces/add`
+- `tests/test_sprint3.py`, `tests/test_sprint5.py`: regression tests for rejected outside-root paths on all four entry points; existing workspace tests updated to use trusted child directories
+- `tests/test_sprint1.py`, `tests/test_sprint4.py`, `tests/test_sprint13.py`: aligned to new trusted-root contract
+- Fix: use `_BOOT_DEFAULT_WORKSPACE` (respects `HERMES_WEBUI_DEFAULT_WORKSPACE` env for test isolation) rather than `_profile_default_workspace()` (reads agent terminal.cwd which may differ)
+- Original PR by @Hinotoi-agent (cherry-picked; branch was 6 commits behind master)
+- 1053 tests total (up from 1051; 2 pre-existing test_sprint5 isolation failures on master, not introduced by this PR)
+
+## [v0.50.33] fix: workspace panel close button — no duplicate X on desktop, mobile X respects file preview (#413)
+
+**Bug 1 — Duplicate X on desktop:** `#btnClearPreview` (the X icon) was always visible regardless of panel state, so desktop browse mode showed both the chevron collapse button and the X simultaneously. Fixed in `syncWorkspacePanelUI()`: on non-compact (desktop) viewports, `clearBtn.style.display` is set to `none` when no file preview is open, and cleared (shown) when a preview is active.
+
+**Bug 2 — Mobile X collapsed the whole panel instead of dismissing the file:** `.mobile-close-btn` was wired to `closeWorkspacePanel()` directly, bypassing the two-step close logic. Fixed by changing `onclick` to `handleWorkspaceClose()`, which calls `clearPreview()` first if a file is open, and falls through to `closeWorkspacePanel()` otherwise.
+
+**Also:** widened the `test_server_delete_invalidates_index` window from 600 → 1200 chars to accommodate the session_id validation guards added in v0.50.32 (#412).
+
+- `static/boot.js`: `syncWorkspacePanelUI()` sets `clearBtn.style.display` based on `hasPreview` when `!isCompact`
+- `static/index.html`: `.mobile-close-btn` onclick changed from `closeWorkspacePanel()` to `handleWorkspaceClose()`
+- `tests/test_sprint44.py`: 10 new regression tests covering both fixes
+- `tests/test_mobile_layout.py`: updated to accept `handleWorkspaceClose()` as valid onclick
+- `tests/test_regressions.py`: widened delete handler window to 1200 chars
+- 1051 tests total (up from 1041)
+
+## [v0.50.32] fix(sessions): validate session_id before deleting session files [SECURITY] (#409)
+
+`/api/session/delete` accepted arbitrary `session_id` values from the request body and built the delete path directly as `SESSION_DIR / f"{sid}.json"`. Because pathlib discards the prefix when `sid` is an absolute path, an attacker could supply `/tmp/victim` and cause the server to unlink `victim.json` outside the session store. Traversal-style values (`../../etc/target`) were also accepted. CVSS 8.1 High (AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:H).
+
+- `api/routes.py`: validate `session_id` against `[0-9a-z_]+` allowlist (covers `uuid4().hex[:12]` WebUI IDs and `YYYYMMDD_HHMMSS_hex` CLI IDs) before path construction; resolve candidate path and enforce `path.relative_to(SESSION_DIR)` containment before unlinking; only invalidate session index on successful deletion path, not on rejected requests
+- `tests/test_sprint3.py`: 2 new regression tests — absolute-path payload rejected and file preserved, traversal payload rejected and file preserved
+- Original PR by @Hinotoi-agent (cherry-picked; branch was 4 commits behind master)
+- 1041 tests total (up from 1039)
+
+## [v0.50.31] fix: delegate all live model fetching to agent's provider_model_ids()
+
+`_handle_live_models()` in `api/routes.py` previously maintained its own per-provider fetch logic and returned `not_supported` for Anthropic, Google, and Gemini. Now it delegates entirely to the agent's `hermes_cli.models.provider_model_ids()` — the single authoritative resolver — and `_fetchLiveModels()` in `ui.js` no longer skips any provider.
+
+**What each provider now returns (live data where credentials are present, static fallback otherwise):**
+- `anthropic` — live from `api.anthropic.com/v1/models` (API key or OAuth token with correct beta headers)
+- `copilot` — live from `api.githubcopilot.com/models` with required Copilot headers
+- `openai-codex` — Codex OAuth endpoint → `~/.codex/` cache → `DEFAULT_CODEX_MODELS`
+- `nous` — live from Nous inference portal
+- `deepseek`, `kimi-coding` — generic OpenAI-compat `/v1/models`
+- `opencode-zen`, `opencode-go` — OpenCode live catalog
+- `openrouter` — curated static list (live returns 300+ which floods the picker)
+- `google`, `gemini`, `zai`, `minimax` — static list (non-standard or Anthropic-compat endpoints)
+- All others — graceful static fallback from `_PROVIDER_MODELS`
+
+The hardcoded lists in `_PROVIDER_MODELS` remain as credential-missing / network-unavailable fallbacks. `api/routes.py` shrank by ~100 lines. Updated 2 tests to reflect the improved behavior.
+
+- 1039 tests total (up from 1038)
+
+## [v0.50.30] fix: openai-codex live model fetch routes through agent's get_codex_model_ids()
+
+`_handle_live_models()` was grouping `openai-codex` with `openai` and sending `GET https://api.openai.com/v1/models` — which returns 403 because Codex auth is OAuth-based via `chatgpt.com`, not a standard API key. The live fetch silently failed, so users only ever saw the hardcoded static list.
+
+- `api/routes.py`: dedicated early-return branch for `openai-codex` that calls `hermes_cli.codex_models.get_codex_model_ids()` — the same resolver the agent CLI uses. Resolution order: live Codex API (if OAuth token available, hits `chatgpt.com/backend-api/codex/models`) → `~/.codex/` local cache (written by the Codex CLI) → `DEFAULT_CODEX_MODELS` hardcoded fallback. Users with a valid Codex session now get their exact subscription model list including any models not in the hardcoded list.
+- `api/routes.py`: improved label generation for Codex model IDs (e.g. `gpt-5.4-mini` → `GPT 5.4 Mini`)
+- `tests/test_opencode_providers.py`: structural regression test verifying the dedicated `openai-codex` branch exists and calls `get_codex_model_ids()`
+- 1038 tests total (up from 1037)
+
+## [v0.50.29] fix: correct tool call card rendering on session load after context compaction (closes #401) (#402)
+
+- `static/sessions.js`: replace the flat B9 filter in `loadSession()` with a full sanitization pass that builds `origIdxToSanitizedIdx` — each `session.tool_calls[].assistant_msg_idx` is remapped to the new sanitized-array position as messages are filtered; for tool calls whose empty-assistant host was filtered out, they attach to the nearest prior kept assistant
+- `static/sessions.js`: set `S.toolCalls=[]` instead of pre-filling from session-level `tool_calls` — this lets `renderMessages()` use its fallback derivation from per-message `tool_calls` (which already carry correct indices into the sanitized message array); the fix eliminates the "200+ tool cards all on the wrong message" symptom on context-compacted session load
+- `tests/test_issue401.py`: 8 regression tests — 4 static structural checks and 4 behavioural Node.js tests covering index remapping, multiple consecutive empty assistants, no-filtering pass-through, and `tool`-role message exclusion
+- Original PR by @franksong2702 (cherry-picked onto master; branch was 31 commits behind)
+- 1037 tests total (up from 1029)
+
+## [v0.50.28] fix: expand openai-codex model catalog to match DEFAULT_CODEX_MODELS
+
+`_PROVIDER_MODELS["openai-codex"]` only listed `codex-mini-latest`, so profiles using the `openai-codex` provider (e.g. a CodePath profile with `default: gpt-5.4`) showed only one entry in the model dropdown. Updated to mirror the agent's authoritative `DEFAULT_CODEX_MODELS` list: `gpt-5.4`, `gpt-5.4-mini`, `gpt-5.3-codex`, `gpt-5.2-codex`, `gpt-5.1-codex-max`, `gpt-5.1-codex-mini`, `codex-mini-latest`. Added 2 regression tests.
+
+- 1029 tests total (up from 1027)

 ## [v0.50.27] feat: relative time labels in session sidebar (#394)
 
 - `static/sessions.js`: new `_sessionCalendarBoundaries()` (DST-safe via `new Date(y,m,d)` construction), `_localDayOrdinal()`, `_formatSessionDate()` (includes year for dates from prior years); `_formatRelativeSessionTime()` now uses calendar midnight boundaries consistent with `_sessionTimeBucketLabel()` — no more label/bucket mismatch; all relative time strings call `t()` for localization; meta row only appended when non-empty (removes redundant group-header fallback); dead `ONE_DAY` constant removed

+# Contributing to Hermes WebUI
+
+Thanks for contributing.
+
+Hermes WebUI is intentionally simple to work on: Python on the server, vanilla JS in the browser, no build step, no bundler, no frontend framework. The best pull requests preserve that simplicity while solving a real problem cleanly.
+
+## Two Paths to a Strong Pull Request
+
+### Path 1: Small, Focused Changes
+
+This is the fastest path to review and merge.
+
+- Fix one clear bug or add one tightly scoped improvement
+- Touch the fewest files you can
+- Avoid drive-by refactors mixed into functional changes
+- Run the relevant tests locally before opening the PR
+- Keep the PR description concise and specific
+
+These are the changes that are easiest to review and safest to merge quickly.
+
+### Path 2: Bigger Changes
+
+If you want to change architecture, reshape a workflow, add a substantial UI feature, or alter core behavior, align on direction first.
+
+- Open an issue, start a discussion, or open a draft PR early
+- Explain the problem you are solving, not just the implementation you want
+- Call out tradeoffs, migration risk, and any alternatives you considered
+- Keep the final PR easy to review by separating unrelated work
+
+Large changes are welcome, but surprise rewrites are hard to review well.
+
+## What We Expect in Every PR
+
+### 1. One Logical Change Per PR
+
+Keep each PR focused. A small related group of fixes is fine. A bug fix plus a CSS cleanup plus a refactor plus a docs rewrite is not.
+
+### 2. Local Verification
+
+Run the test suite locally:
+
+```bash
+pytest tests/ -v --timeout=60
+```
+
+CI also runs this suite on Python `3.11`, `3.12`, and `3.13`.
+
+If your change affects browser behavior, also run the relevant manual checks from [TESTING.md](TESTING.md).
+
+### 3. Clear PR Description
+
+There is currently no PR template in this repo, so include the important sections yourself:
+
+- Thinking Path
+- What Changed
+- Why It Matters
+- Verification
+- Risks / Follow-ups
+- Model Used
+
+If the change is user-visible, include screenshots or a short video.
+
+For UI or UX changes, before/after images are required. PRs that change the interface or interaction flow without before/after images will likely be ignored, or closed in a regular maintainer sweep without review.
+
+### 4. AI Usage Disclosure
+
+If AI helped produce the change, say so in the PR description.
+
+Include:
+
+- Provider
+- Exact model name or ID
+- Any notable mode or tool use that mattered
+
+If no AI was used, write: `None — human-authored`.
+
+### 5. Keep the Docs Honest
+
+If your change alters behavior, architecture, testing, setup, or user-facing workflows, update the relevant docs in the same PR.
+
+Common files:
+
+- [README.md](README.md) for setup, usage, and contributor-facing commands
+- [ROADMAP.md](ROADMAP.md) for shipped features and sprint history
+- [ARCHITECTURE.md](ARCHITECTURE.md) for implementation details and design constraints
+- [TESTING.md](TESTING.md) for manual and automated verification guidance
+- [CHANGELOG.md](CHANGELOG.md) when maintainers want release-note-ready entries
+
+## Project-Specific Guidelines
+
+### Preserve the Design Constraints
+
+Hermes WebUI is deliberately:
+
+- No build step
+- No bundler
+- No frontend framework
+- Easy to modify from a terminal
+
+Do not introduce new infrastructure or dependencies unless the gain is clear and the tradeoff is justified.
+
+### Match the Existing Shape of the Codebase
+
+- Server logic belongs in `api/` with `server.py` staying thin
+- Frontend behavior belongs in the existing `static/*.js` modules
+- Prefer extending current patterns over introducing parallel abstractions
+- Keep changes legible to future contributors working directly from the repo in a terminal
+
+### Be Careful With User-Facing Changes
+
+This project is heavily UI-driven. If you change interaction flows, session behavior, workspace browsing, onboarding, or mobile layouts:
+
+- test the happy path
+- test reload behavior where relevant
+- test narrow/mobile layouts where relevant
+- include before/after images in the PR
+
+### Security and Safety Matter
+
+This app can expose workspace contents, run agent actions, and optionally sit behind a reverse proxy or Docker deployment. Treat auth, path handling, uploads, streaming, and environment handling as high-risk areas.
+
+If your PR touches security-sensitive behavior, say so explicitly in the PR description and explain how you verified it.
+
+## Writing a Good PR Message
+
+Start with a short Thinking Path that explains the chain from project goal to the specific fix.
+
+Example:
+
+> - Hermes WebUI aims for near 1:1 parity with the Hermes CLI in a browser
+> - Long-running chat turns rely on SSE streaming and session recovery
+> - Reloading during an in-flight turn can leave the UI in an inconsistent state
+> - The bug was that recovered sessions restored messages but not the live stream state
+> - This PR fixes the recovery path so in-flight turns reconnect cleanly after reload
+> - The benefit is that users can refresh or reconnect without losing visibility into active work
+
+Another example:
+
+> - Hermes WebUI is intentionally a simple Python + vanilla JS application
+> - The right panel is used for workspace browsing and previews
+> - On mobile, panel state changes need to be obvious and touch-friendly
+> - The existing close affordance was inconsistent with the bottom-nav flow
+> - This PR fixes the mobile panel close behavior and aligns it with the current navigation model
+> - The result is fewer dead-end UI states on phones
+
+After that, cover:
+
+- what you changed
+- why you changed it
+- how you verified it
+- what risks remain
+
+## Review Tips
+
+Want the smoothest review?
+
+- Keep diffs tight
+- Name things clearly
+- Avoid unnecessary rewrites
+- Add short comments only where the code would otherwise be hard to follow
+- Respond directly to review feedback and update the PR description if the scope changes

+Regression tests for issue #401 / PR #402:
+Tool call cards show incorrect/duplicate entries on session load after context compaction.
+
+Root cause: loadSession() applied its own B9 sanitization (producing a new message array
+with different indices) but did not remap the session-level tool_calls.assistant_msg_idx
+values to match. It then assigned the broken tool_calls directly to S.toolCalls, bypassing
+renderMessages()'s fallback that correctly derives tool calls from per-message tool_calls.
+
+Fix: build origIdxToSanitizedIdx during the B9 pass and remap each tc.assistant_msg_idx;
+set S.toolCalls=[] so renderMessages() uses the fallback derivation.
+
+These tests verify the JS logic statically (no server needed).

+Root cause: _provider_api_key_present() only knew about the four providers in
+_SUPPORTED_PROVIDER_SETUPS.  For any other provider it returned False, causing
+chat_ready=False, which made the wizard fire even when the user was fully
+configured.  The second part of the fix ensures _saveOnboardingProviderSetup()

+     MINIMAX_CN_API_KEY is in env (via hermes_cli.auth.get_auth_status)
+  2. _status_from_runtime gives chat_ready=True for minimax-cn with a key set
